At the end of
SSS (or at least one of the endings to SSS), Alessia used her superior mind control techniques to wipe herself from everyone's mind, including yours - so that should could effectively go into hiding (or something). However your strong mind resisted and you occasionally have brief flashbacks of what really happened.
There were so many paths and choices in SSS that never got carried forward into SSS. The author picked the "canon" version of the story and that is the assumed starting point for Cuntswell.
Professor Matsumoto was her old student of the dark arts. So she is still aware of Alessia, even though the MC is barely aware she existed. Matsumoto, if I remember correctly, is the student who Alessia lost control of. She may even be more powerful than Alessia - who knows...
The game is currently on hold.
Cuntswell got flagged by

. He also had another game (
Where Bad Girls Go) he was planning for the future, which I guess he brought forward to keep the Patreon subscribers happy. He was developing both games at the same time for a while.
My guess is that he found he was spreading himself too thin and decided to concentrate on one game. For whatever reason, he picked WBGG. He has stated that Cuntswell isn't abandoned and that he plans to return to it once WBGG is finished. Though obviously, nobody can predict the future. He also had a note, I think on his Subscribestar page for a while, that he had a 2nd
SSS spin off game in mind too. My point being, I don't think he's giving up on these stories.
So future updates... not any time soon. But eventually™.
